If in the bottom of the bucket with water we made a hole, then water flows out of it. Bucket with water is the system with ##m(t)##, thus we have to use equation:

##m(t)\frac{dv}{dt} = F + u\frac{dm}{dt}##.

Where ##u\frac{dm}{dt}## -- is jet reaction force.

But, I think the jet reaction force should not appear in this case. What is the solution of this paradox?
